The T Series extra heavy-duty Grade 1 cylindrical lock is designed to stand up to high-traffic and heavy-abuse applications. The lock can accept any manufacturer’s cylinder, and the cylinder can easily be removed for quick, easy re-keying, so retrofitting a current building is simple.

The T Series is constructed with a compression spring that allows the lock to exceed ANSI/BHMA Grade 1 testing requirements. Perfect for high-use institutional applications, the T Series lock delivers by providing a solid product at a solid price.
